Laws of Chemical Combination — Chemistry Keypoint

Laws of Chemical Combination

There are four laws of chemical combination, which describe the general qualities of a chemical change.

  1. Law of Conservation of mass states that matter is neither created nor destroyed but can be transformed from one form to another.
  2. Law of definite proportions states that all Pure Sample of a particular chemical compound contain the same number of elements mixed in the same proportion by mass. This law is also known as law of constant composition.
  3. Law of multiple proportions — It states that when two elements x and y combine to form more than one compound, then the several masses of element, x, which combine with a fixed mass of the other element, y are In a simple multiple ratio.
  4. Law of reciprocal proportion — It states that the masses of several elements A, B, C, which combine separately with a fixed mass of another element, D, are the same as the messes in which A, B, C themselves combine with one another.
